Do you have a sense of how many properties are owned by folks from other countries, as a percentage of the total housing stock? The national association of realtors[0] put out a press release saying their purchases accounted for about 1.6% from April 2021 through March 2022, however it's not clear from their figures whether that is all existing homes or a mix of new and existing. If that is right that doesn't seem too bad, at least for a year. Dunno what the total ownership stats say.
